IMPROVEMENT IN PUMPS.

Specification forming part of Letters Patent No. 163,766., dated May 25,1875 application filed April 10, 1875.

To all whom it may concern Be it known that I, D. J. GORTON, of Quincy,in the county of Adams and State of Illinois, have invented certain newand useful Improvements in Pumps; and I do hereby declare the followingto be a full, clear, and exact description -of the invention, such aswill enable others skilled in the art to which it pertains to make anduse it, reference being had to the accompanying drawings, which formpartof this specification, in which is shown a vertical central section ofmy invention.

The object of this invention is to provide an improved suction and forcepump, which shall be adapted to deep wells, certain and constant inoperation, productive of ample discharge, and not liable to get out oforder or freeze under ordinary conditions.

The pump to which my improvements particularly relate possesses thefollowing-described characteristics: The body of the pump consistsessentially of two Vertical barrels or cylinders, the principal one ofwhich extends from the top of the well t-o the water, while the otherterminates above the water. These two barrels are joined together sideby side. The shorter barrel is surmounted by a castor sheet metalcylinder, within which the plunger works. The longer barrel is dividedby a horizontal diaphragm or partition into two sections, which havecommunication through the shorter barrel near its lower ends by suitableapertures provided with ilap-valves, one of which opens into the shorterwhile the other opens into the longer barrel or tube. When the plungerrises the lower valve is opened and the water enters the suction-tube,and when the plunger descends the lower valve closes while the upper oneopens, whereupon .the water previouslydrawn up is forced into the uppersection of the long` tube from which it eventually flows to supply thedemands.

My invention, then, consist-s, irst, in providing the inner surfaces ofthe barrels with convex protuberances above the valves, for the purposeof deflecting the descending currents ofwater, so that the same shallstrike directly against the backs of the valves, and not have a tendencyto force and hold the latter open when they should be closed. Secondly,in providing the long barrel of the pump with a small orifice below thefreezing-point, and in such a position that the escaping waste may spurtagainst the piston rod and thence flow down into the cylinder, causingthe plunger to be always covered a suficient depth to prevent the accessof air fromabove and freezing in the upperl portion of the long barrel.

Referring to the accompanying drawings, A A designate the two barrels ofa suction and force pump, constructed according to my invention. Brepresents the diaphragm or partition dividing the longer barrelA intotwo sections, which communicate alternately with the barrel A near itslower end, and through oriiices C C, provided with flap-valves D D',respectively, the valve D being arranged to open into the barrel A whenthe plunger is raised, and the valve D to open into the barrel A whenthe plunger is lowered, said valves opening and closing alternately. d ddesignate springs arranged to bear against the outer or back surfaces ofthe valves for the purpose of insuring certainty and rapidity of action.e c are convex protuberances, by means of which the descending currentsof water are deflected and caused to strike directly against the backsof the valves, throwing them forward and closing them beyond thepossibility of said currents striking their faces and holding them open.The shorter, or plunger, tube A is surmounted by a cast or sheet metalcylinder, preferably galvanized, in which the plunger works. As theplunger asceuds the suction opens the lower valve D, allowing the waterto rise and enter the plunger-barrel from the lower section of thelonger barrel, the upper valve being at the same time closed. Uponlowering the plunger the upper valve opens, while the lower one closes,whereupon the water, previously raised by suction, is forced upwardthrough the upper section of the barrel A, whence it escapes through thespout E. At each rise of the water to the spout a small quantity entersthe reservoir F, located at the upper end of, and communicating with,the long barrel, and tends to keep the discharge uninterrupted duringthe intervals succeeding the descent of the plunger. G is the orifice inthe side of the barrel A, below the platform of the pump,

, ter than the cylinder, by about two thicknesses of packing. The latteris crimped and cupped upon the blocks 7c in the manner shown by thecylinder, which renders it more elastic and expansive than when cuppedby the center disk alone. rEhe sections or partsv of the plunger aresecured upon the plungerrod by means of nuts or other suitablefastenings.

Having fully described my invention, I claim- 1. The protuberances c e,in combination With the valves D D', substantially as dcscribed.

2. The barrel A, having the orifice G, as and for the purpose specitied.

In testimony that I claim the foregoing, I have hereunto set my handthis 22d day of March, 1875.
